20 CHEMISTRY. 
and it is combinations of oxygen which constitute the greater portion of 
the mineral, vegetable, and animal kingdoms. Many compounds of oxygen 
are produced at elevated temperatures alone. Under these circumstances, 
the heat which is liberated in almost all chemical combinations, and 
especially those between elements having a great affinity for each other, is 
set free in large quantities, thus serving to heat fresh matter. Many 
substances do not combine quite so readily with each other, and with many 
the temperature must be elevated to a very great degree to bring abovt the 
desired result.
